One of the aims of government policy has been to speed up the diffusion of new technologies. This aim has been pursued largely by policies aimed at improving information about the technology or by subsidising the purchase of new technology. In this paper we construct a simple diffusion model...

This Paper analyses the welfare benefits from falling relative prices of IT (Information Technology) goods across a wide range of countries. Using two separate methodologies and datasets, we find that welfare benefits mainly accrue to users of IT, not their producers, because of falling relative...

We examine a model of R&D competition and cooperation in the presence of spillovers. Unlike virtually all the literature, however, we treat these spillovers as endogenous and under the control of firms. We show that it is then essential to make a number of distinctions that are ignored in the...

We consider an endogenous growth model that includes international trade in capital goods. The model yields several distinct balanced growth solutions that can be classified using stability under adaptive learning. Some of the equilibria can involve growth rates much higher (or lower) than...

This Paper analyses the impact of R&D subsidies on incumbent firms to introduce new goods. We are especially interested in investigating various consequences of government subsidies for R&D, provided to firms that offer products of different qualities. This study examines the incentives of...

We develop a model of growth driven by successive improvements in `General Purpose Technologies' (GPTs), such as the steam engine, electricity, or micro-electronics. Each new generation of GPTs prompts investments in complementary inputs and impacts the economy after enough such compatible...

This paper surveys the recent economic history of Western European growth. It concludes that this experience has been disappointing and that further reforms are desirable in many countries. The requirement for reform comes both from achieving 'close-to-frontier' status and from the opportunities...
